The Indian Space Research Organisation will on Thursday launch a navigation satellite, the eighth such satellite to be a part of a constellation, from Sriharikota, the space agency said on Tuesday.

PSLV-C41/IRNSS-1I Mission is scheduled to be launched on Thursday morning at 4.04am.

IRNSS-1I is expected to replace IRNSS-1A, the first of the seven navigation satellites, that was rendered ineffective after its three rubidium atomic clocks failed. The seven satellites are part of the NavIC navigation satellite constellation.

The launch will be ISRO’s second attempt at sending a replacement satellite.
